Twelve microsatellite markers on chromosome 6 were analyzed in German Holstein population to detect and locate QTL affecting daily body weight gain (DBWG). The results indicate promising location for QTL controlling daily body weight gain trait on chromosome 6. Where, three markers BMS2508 BM3026 and TGLA37 at three different positions in a distance 15.2 cM on BTA6 were associated with significant effects for daily body weight gain trait (DBWG). Comparison between this finding and previously identified QTL support the location of a QTL for growth traits on chromosome 6, where a significant QTL for birth and yearling weight was previously identified on chromosome 6 tightly close to marker BM3026. Finding from this study could be used in subsequent fine-mapping work and applied to marker-assisted selection (MAS) of production traits.

Sire variances for 30 conformation traits on Canadian Holsteins were estimated on the underlying continuous scale using a single trait threshold linear model. Data were linearized first classifications on 66 617 cows by 3305 sires, classified since February 1988. The model included a random sire effect and fixed effects of herd-round of classification-classifier, age at classification and stage of lactation at classification. Sires were assumed unrelated in this study. Variance components for sires were estimated by REML EM algorithm. Estimates of heritabilities were generally larger than those currently used in genetic evaluation for type traits in Canadian Holstein population. The new heritabilities are recommended for use in a traditional linear animal model procedure. Key words: Variance components, threshold model, type traits
